They are the same species (European Rabbit), but they are different breeds.
As far as I can tell, they are. I had heard of Netherland dwarves but not Norwegians, so I went about looking this up. My best guess is that the Norwegian dwarf rabbit is just a misnomer for the Netherland dwarf, one which has somehow and sometimes stuck--but it is a mistake. People are not that great with geography. It's just a guess, but it's a good one. Regardless, that's a wonderful tiny bunny.
No, there are small breed like the Netherland Dwarf Rabbit and HUGE breeds like the Flemish Giant! And everything in between! :-I
If your English lop is a male and the nether land dwarf is a female then the lop might try to mount the female nether land and squash (kill) it. Its better to buy a smaller cage for the dwarf and keep them in separate cages since dwarfs don't need a lot of room.
Netherland dwarf rabbits can and can't eat the exact same food as all pet rabbit breeds. The lists below say that all parts of the cherry tree, except for the fruit itself, are poisonous to rabbits, although the flowers (blossoms) are not mentioned specifically. Better safe than sorry, so you might want to avoid giving your rabbit any cherry blossoms. See the related questions below for more information about rabbit care. All the information applies to Netherland dwarfs as well as all pet rabbit breeds.
your rabbit is most likely a mix of the two if not they probably just resemble each other. make sure your rabbit is full blooded dwarf-lop.
Care of the Netherland dwarf goat should include getting your goat a friend. These are herd animals. Keep the goats living area clean. Feed the goat and be sure there is fresh drinking water. It should also get veterinary care as needed.

You can find out whether your dwarf rabbit is male or female in the same ways that you can find out whether any pet rabbit is male or female -- dwarfs are no different from other rabbits in this sense. See the related question (linked below) for details and links.
No. A dwarf star is a small star. A white dwarf is just one particular type of dwarf star, but there are other types.
Dwarf rabbits have the same genitalia as other pet rabbits. The only way to know for sure if a pet rabbit is male or female is to examine the genitalia. See the related question below for details.
